To aZZ whom it may conccm:

Be it known that we, CLARENCE FREDERIC DAVY and THoMAs RIcHAnDsoN, bothcitizens of the Dominion of New Zealand, and residing at Fitzroy, in theProvincial District of Taranaki, in the Dominion of New Zealand, haveinvented certain new and useful Inprovements in Non-Refillable Bottles,of which the following is a specification.

This invention relates to that class of bottles which are constructed toprevent fraudulent refilling.

According to our invention, a cylinder having a closed top is adapted tofit the neck of a bottle, the said neck having an internalcircumferential recess into which project a Washer of cork, rubber orsimilar resilient material held in a groove upon the exterior of thecylinder, and crescent shaped members having a pad of cork or the likemidway between their extremities, the said members being held in anothergroove also upon the eXterior of the cylinder. Instead of crescentshaped members a gapped ring or a second ring of cork, may be employed,or an extra ring of cork. At the top of the cylinder is a fiange havingmutilations, which are out of register with corresponding mutilations inanother fiange lower down upon the cylnder. Below these fianges thecylinder is provided with lateral ports. The interior of the top of thecylinder is recessed upwardly. A sleeve having a groove fitted with awasher of cork, rubber or similar resilient material to fit the interiorof the cylinder has a fiange which fits against the bottom of thecylinder. The sleeve has lateral ports which do not register with thelateral ports of the cylinder. A hollow piston or plug, slidable in thesleeve, and adapted to seat upon a seating formed at the bottom of thesleeve, closes the ports of the sleeve during the movement of the bottlefrom an inverted to an upright' position. A ball, heavier than water, islocated within the cylinder, and is adapted to push the piston into thesleeve by gravity. A second ball, located within the piston and lighterthan water has a seating formed upon the aforementioned internal fiangeof the sleeve.

In a modification the invention is adapted for use upon bottles forcontaining sauces, patent medicines and the like.

The drawing herewith llustrates the invention.

Figure 1, is a sectional elevation of a bottle embodying our invention.Fig. 2, is a plan of the cylinder. Fig. 3, is a sectional plan on lineA-A Fig. 1, and Fig. 1. a sectional plan on line B-B Fig. 1. Fig. 5, isa perspective view of a gapped ring. Fig. 6, is a sectional elevationshowing a modified form of our invention.

Referring to the drawing, the cylinder 1 has a closed top 2 and isadapted to fit the neck 3 of the bottle 1 by means of a cork, rubber orthe like washer 5, which is held in a groove 6 formed upon the eXteriorof the cylinder, and is adapted to swell into a recess 7 after beingsqueezed. into the recess 6 during the operation of inscrting thecylinder into the neck of the bottle. If the washer 5 should deteriorateor be destroyed, it might be possible to extract the cylinder, refillthe bottle and replace the cylinder. To prevent such fraudulent actioncrescent shapcd members S and 9 (see Fig. L) are fitted into a groove 10also formed upon the eXterior of the cylinder.

Cork pads 11 and 12 are fixed to the niembers 8 and 9 midway betweentheir eXtremities. The cork allows the members 8 and 9 to pass into thegroove 10 while the cylinder is being inserted into the neck of thebottle and forces the said members partially into the recess 7. Thesemembers thus render it impossible to withdraw the cylinder as theyextend into the recess 7. At the top of the c ylinder is a flange 13mutilated by gaps 14; (see Fig. 2) which gaps are out of register withthe gaps 15 of a correspondingly mutilated ange 16 located lower downupon the cylinder. The gaps in the flanges 13 and 15 allow liquid topass out of the bottle but prevent the introduction of a wire tor thefraudulent purpose of tamperingwith the parts contained 111 the interierof the' cylinder. Below the fiange 16 the cylinder 1 is provided withlateral ports 17, and the top of the cylinder has an internal sphericalrecess 18.

A sleeve 20, having a groove 21, filled with a cork, rubber or the likewasher 22 to fit the interior of the cylinder l, has a fiange 23 whichfits against the bottom of the cylinder l. The sleeve has lateral ports2 1 which do not register with the ports 17. A hollow piston or plug 25slidable in the sleeve 20 clcses the ports 2 1 when the said piston orplug is at rest upon the internal fiange 29, as shown in Fig. 1. A ball26 heavier than water is located within the oylinder l, and is adaptedto push the piston 25 into the sleeve 20 by gravity. The radius of theball 26 is less than the radius of the recess 18, so that the ball isnot held by suction, but will readily run down upon the piston, when thebottle is partially in verted. A second ball 27 lighter than water andlocated within the piston, hasa seating 28 for-med upon thebeforementioned fiangc 29. If the pressure is applied to the mouth ofthe bottle, the sleeve 20, balls 26 and 27 the piston 25 and the washer22 would be forced into the bottle, which might then be refilled. Butthe fact that the above parts were present in the liquid contaned by thebottle would be ample evidence that the con tents has been tamperedwith, and would prevent a purchaser from buying a bottle so tamperedwith.

The members 8 and 9 may be made of glass, or other suitable material. Ifthe members are made of reslient material the cork pads 11 and 12 arenot necessary, and the members may then be made in one piece in theshape of a ring 30 with a` gap 31, see Fg. 5.

`When the bottle is inverted for the urpose of pouring out liquids, theball 26 falls away and the piston descends beyond the ports in thesleeve, thus allowing the liquid to flow through the said ports, throughthe ports in the cylinder, and through the gaps in the fianges 13 and16. An air hole 13 in the cylinder l allows the piston to descendquickly and consequently the liquid fiows at once. Upon returning thebottle to its vertical position the ball 26 falls upon or rolls againstthe piston, which thereby closes the ports in the sleeve. If an attemptis made to fill the bottle while inverted, the ball 27, being floatablein water, will close upon its seat and prevent such fraudulent action.

Fig. 6 shows a modified form of the invention suitable for bottles usedfor containing sauces, patent medicines and the like. The internalsleeve 20 is shortened and the hollow piston 25 is dispensed with.

The balls 33 and 34 are located within the cylinder 35, whichcorresponds to the oylnder 1 previously described. The ball 33 isheavier than water and the ball 34 fioats in water. The cylinder 35 hasports 36 and 37, and the ball 34 has a seating 38 at the bottom of thesleeve 20. The ball 33 falls into the recess 39 formed in'the top of thecylinder and the ball 34 falls back to allow liquid to pass when thebottle is inverted, and the ball 33 closes the ball 34 upon its seatduring the movement of restoring the bottle to its upright position. Ifan attempt is made to fill the bottle with liquid while inverted, theball 34 fioats upon the liquid and stopsits entrance into the bottle.

What we do claim and desire to secure by Letters Patent of 'the UnitedStates is A non-refillable bottle, including a oylinder havingcrcumferential ports intermediate of its length, said cylinder beingprovided around its upper edge with a flange having a plurality ofmutilations therein and a short interval below said flange with a secondfiange also having a plurality of mutilations therein, alternating withthe mutilations of the aforesaid fiange, said cylinder also havingarranged in its lower end a sleeve provided with ports out of registerwith the aforesaid ports of said cylinder, said sleeve having arrangedwithin itself a closed upper end hollow piston and provided With a portin the bottom, a buoyant valve seated in said port and arranged withinsaid piston, said piston itself controlling the ports in said sleeve,and a nonbuoyant valve arranged within the upper end of said sleeve andadapted to engage the closed upper end of said piston and limited in itsupward movement by the upper end of said cylinder.

In testimony whereof we have signed our names to this specification inthe presence of two witnesses.
